FRIEDRICH VON MARTINI, OF FRAUENFELD, SVITZERLAND.

EMBROlDERlNG-NIACHINE.

SPECIFICATION forming part of Letters Patent No. 332,024` dated December8,1885.

Application filed July 10` 1883. Serial No. 100,397. (No model.)Patented in England May 21, 1883, No. 2,5110; in France August 23, 1883,No. 155,238; in Germany April 9, 1884, No. 27,347, and inAustria-Hungary September 17, 1884, No. 6,743 and No. 42,324.

To @ZZ whom it may concern,.-

Be it known that I, FRIEDRICH voN MAR- TINI, a citizen of the Republicof Switzerland, residing at Frauenfeld, Switzerland, have invented acertain new and useful Embroidering- Machine, of which the following` isa specification.

My invention has been patented to me in France on August 23, 1883, No.155,238; Germany on April 9, 1884, No. 27,347; England, May 21, 1883,No. 2,530, and Austria- Hungary on September 17, 1884, No. 6,743 and No.42,324.

rIhese improvements are represented in the drawings accompanying thisspecification as applied to a machine in which the embroidering isproduced by means of a series of needles and shuttles, each needle andshuttle acting to make embroidering-stitches by interlocking threads,ina similar way as the needle and shuttle act in an ordinarysewing-machine.

My invention consists of means for regulating and governing thepantograph, also the constructions composing the clothpresser, take-up,oscillating shuttles, the hole-punching device, and the mechanism forcontrolling and operating such parts, all of which are hereinafterdescribed in the specification, and illustrated in the drawings, andspecifically pointed out in the claims.

It will be understood that while the improvement in the construction ofthe shuttle mechanism can only be applied on embroidering-machines usingneedles and shuttles, the other improvements covered by the claims maybe applied to all embroidering-machines, and as there are many operatingparts of my machine to which I lay no claim, said parts being incidentalto my improvements, I shall not describe these parts with moreminuteness than is necessary to illustrate my improvements.

In the accompanying drawings, Figure I represents a front elevation ofthe left-hand side of the machine. Fig. II representsavertical sectionthrough the machine on line l 2, seen from the lefthand side; Fig. III,the left-hand vertical end elevation; Fig. IV, a vertical cross-sectionthrough the shuttle-bar,

Fig. V, a part plan thereof. Fig. VI (A, B, C, and D) represents, onenlarged scale, the

shuttle, Athe front elevation and B the plan thereof, C a section of thesame, and D a section through the shuttle-casing. Fig. VII represents apart end elevation ofthe right-hand portion ofthe machine, illustratingpart of the driving mechanism and the cloth presser. Fig. VIII is partof asectional front elevation thereof, and Fig. IX part of a sectionalplan of the same. Fig. X is an isometric View of the hole-punchingdevice. Figs. XI, XII, and XIII represent part views in parallelperspective of the mechanism for operating the cloth-presser and thetake-up by means of the to-and-fro movement of thc needle-carriage. Fig.XI shows the mechanism for the transmission of motion from the drivingshaft to the needle-carriage; Fig. XII, mechanism for the transmissionof motion from the drivingshaft and from the connecting-rod of theneedle-carriage to the cloth-presser and Fig. XIII gives the mechanismfor the transmission of motion from the to-aud-fro movement of theneedle-carriage to the take-up, showing also the position of thepulley-guides Tfor the needle-thread and of the needle-thread bobbins,thethread being marked thus Similar letters of reference in differentiigures indicate corresponding parts.

I give iirst the description of all parts in front of thefabric-carrying frame. There are to be found the needle-carriage, theneedlethread bobbins, the pulley-guides for the needle-thread, thetake-ups, and the cloth-pressers. The needle-carriage (see Figs. I, II,III, VII, and IX) having to perform the embroidering proper byintroducing the thread passed through the eyes of the needles into thefabric and to the back side of said fabric, where the thread is engagedby the shuttle of the shuttlecarriage, is constructed, as is generallydone now, with two horizontal rows of eye-pointed needles, N, (see Figs.IV and V,) pointing toward the fabric, and one row above the other beingrigidly fast to clamps N6, which are secured to horizontal straight barsN N", (see Figs. III, IV, XI, and XIII,) said bars being bolted to thetop and bottom ends of vertical brack- This blade is provided with smallholes drilled ets N N3, the middle part of said brackets being securedto the pipe N4, which pipe is provided at both ends and inside of theside frames, F F, of the machine with the slide-blocks N3 N3, and whichpipe is further provided with the cross-heads N2 N2. slides on theguide-bars F3 F3 forward and backward, said guide-bars being bolted tothe frames F F of the machine. The to-and-fro movement of theneedle-carriage, as may be more plainly seen in Fig. XI, is effectedfrom the driving-shaft D by means of connectingrods, one at each end ofthe carriage.

On the left-hand side ofthe machine, where the pattern-board is located,and between the main frame F and the frame F3, the drivingshaft isdouble crooked, so as to form av crank, D, which is shown in thedrawings. (See Fig. XI.) The connecting-rod N connects said crookedportion of shaft D with the lefthand end of the needle-carriage by meansof the cross-head N2 in Fig. I, converting thus the revolving movementof the crank D14 and the driving-shaft D into the to-and-fro movement ofthe needle-carriage. AOn the righthand side of the machine, however, thedriving-shaft D is provided with an eccentric-disk, D22, as may be seenin end elevation in Fig. VII, and in plan, Fig. IX. Said eccentricdiskD12 is provided with a pin, D23, which is secured to said diskeccentrically with regard to shaft D, and unto this pin theconnectingrod N is sleeved, connecting the same with the right-hand sideof the needle-carriage by means of cross-head N2. (See Fig. III.)

At about the same height with the straight bars N3 N3, and carried bythe hollow lengthbeams F F2, of U-shaped cross-section, (see Figs. I andII,) are the needle-thread bobbins T3, placed vertically,on whichbobbins the needle or embroidery thread is wound, said thread ruimingthrough the pulley-guides for the needle-thread T T, and through thetake-up to the eyes of the needles. It must be observed that becausethere are two rows of five needles there must also exist for each row acorresponding row of bobbins, pulley-guides for the needle-thread, andtake ups, and thus two systems will be formed almost perfectly alikeanupper one and a lower one-which two systenis perform each the same work.

The parts marked with T T in Figs. I, II, and XIII are pulley-guides forguiding the thread from the bobbin N0 to the take-up.

The take-up or thread-tightener consists of a shaft, T, mounted inbearings T2 T2. (See Figs. II and XIII.) These bearings are cast in onepiece with the brackets for the pulleyguides T for the needle-thread,and are screwed rigidly fast onto the hollow beams F and F2, becausethere are two series or rows of needles in the machine illustrated;also, two such beams, F F2, and two such shafts, T', are to be found.yEach shaft carries a suitable number of levers, T3 T3, keyed thereon,said levers supporting a flat straight bar or blade, T4.

This needle-carriagev therein, one hole for each thread. In each seriesof needles, therefore, the needle-thread which is wound onto the bobbinsT0 passes through the pulley guides T for the needlethread, and throughthe holes in the bar T* to the needles. (See Figs. II, V, and XIII.) Thelevers T3, at each end of the shafts T, are made angular-that is to say,to each a horizontal arm is cast on-and the horizontal arms of the twoangular levers T3 on the upper shaft T are connected by means of theconnecting-rods T5 with the ends of the horizontal arms of the twoangular levers T3, which are mounted on the lower shaft T. These shaftsare located inside of the hollow beams F and F2, respectively, and thevertical arms of the levers T3 are reaching through slots in the topwalls of said beams to the outside of the same. Any oscillating movementof one shaft T must necessarily be shared Ain by the other shaft T. Theupper angular levers, T3, receive an oscillating motion by means of acontriv'ance to be described hereinafter, said movement derived from andcorresponding with the to-and-fro motion of the needle-carriage. Saidcontrivance for oscillating the angular levers T3 exists in double, onefor each side of the machine, and it is partly attached to the upperbeam, F, and to the brackets N3 l at each end of pipe N4.

The contrivance shown in Figs. XIII and l' 3 II consists of a bracket,A", bolted to the vertical bracket N 3. Said bracket carries twoadjustable screws, A A2, set opposite each other and screwed into twosuitable lugs cast onto bracket A". Between these screws A A2 aneccentrical segment, A, is thrown hither and thither, according to theforward or backward position of the needlecarriage. The eccentricalsegment A swings on a fulerum, which is a pin rigidly fast to a bracket,A3, said bracket being secured to beam F. The segment Acarries pin A,(see Fig. II,) against which, owing to the reciprocating motion of theneedle-carriage, screws A and A2 are pushing, and at the top of saideccentrical segment A two hollows, A5 and A3, are provided, receivingalternately the friction-roller T3 of levers T3 T3, raising the camroller T3, and therebythe horizontal arm of lever T3, whenever saidroller snaps into hollow A3, and

lowering it whenever said roller T6 snaps into A3. Cam-roller T6 willsnap into said hollows A5 or A3, because the weight of the horizontalarms of levers T3 and of the connecting-rod T3 is sufficient to causesaid roller T6 to rest on and bear against the periphery of theeccentrical segment A. The horizontal arms of levers T3 will swingdownward whenever the needle-carriage approaches the fabric-carryingframe, and will swing upward whenever the needle-carriage moves oft', orwhen the needles are withdrawn out of the fabric. By this change ofposition of said levers T3 blade T4 will: also change position and thethread will be more or less stretched or IOO IIO

ISO

tes

slackened. It will be slackened when the perforated blade T* of thetake-up swings toward the needles, which occurs when the needles enterthe fabric, and the thread will be tightened, when the blade T* of thetakeup swings off from the needles, which will occur when the needlesare withdrawn from the fabric in the moment when the loops of theneedle-thread have been engaged by the shuttles, and when the stitcheshave to be tightened up. In this moment it will be necessary to holddown the fabric, said fabric 1 being merely stretched within the frameC,

and offering, therefore, not enough resistance to the pull of theneedles and thread, and this is accomplished by the cloth-pressers. Thecloth-presser being required for both rows of needles, in order toprevent any distortion of the fabric and of the embroidery thereonduring the tightening up of the stitches, is similarly constructed, asit has been done heretofore; but it derives its motion in a differentway from the usual manner. A rail of angle-iron, H0, which exists ineach of the two series of needles running all along the fabric beneaththe line of the needles, (see Figs. II and X,) and being provided withholes for the hole-punching awls, which will be described hereinafter,is supported by the extremities of the upper arms, H, of angular leverswhich are swinging on pins H, said pins H being rigidly secured onbrackets H3, (see Fig. VIL) which brackets are bolted to the sideframes, F, of the machine. The horizontal arms H IP of these angularlevers are connected together by connecting-rods H5 H5, and saidconnecting-rods,which occur on each side of the machine, are engaged bypins secured at the ends of the short levers H9, (see Figs. VII and IX,)said pins engagging suitably-slotted parts provided on the rods IP.Levers H and H9 are secured rigidly fast to the small shafts H8, saidsmall shafts HS occurring on each sideof the machine once, and beingjournaled in bearings cast onto both side frames, F. Levers H carry attheir extremities the journaled rollers H7 H7, and are set in such a wayon the small shafts HB that said rollers are pressed downward by contactwith the oscillating connecting-rod N. In order to secure fully thatrollers H7 follow the rods N when the same oscillate upward, helicalcontracting-springs H1", as shown in Fig. XII, may be attached ontoframes F, and to the pins at the ends of levers H6, which pins areengaging the slotted parts on the connecting-rods IF. These helicalsprings have been omitted in Figs. VII and IX, as not being absolutelynecessary, and in order not to obstruct unnecessarily the drawings. Theweight of the rails H0 is sufficient to act in such a way through theangular levers H H2 and rods H5 andlevers H6 and H9,that rollers H7 arebearing upward and against the connecting-rods N. When saidconnectingrod N is in its upper position,the rails H0 will be pressingagainst the fabric, owing to their own gravity. When, however, saidconnecting rod oscillates downward, the rails H0 will be swung off fromthe fabric, because rollers H7 are pressed downward by said rods N', andthus the fabric which was lheld down by rail H0 during the tighteningofthe stitches will be relieved again from the contact with rail H0, andtherefore said fabric may follow the movement imparted to thefabric-carrying frame by the pantograph P and handle-rod P during thechange of the stitches.

In the rear of the fabric-carrying frame aud facing it theshuttle-carriage is located, resting on the saine slides with theneedle-carriage, but stationary while the machine is at work, saidshuttle-carriage being made to slide back from the fabric-carrying frameonly for convenience sake whenever a cloth is stretched on said frame.The arrangement for sliding back the shuttlecarriage consists iu shaft E(see Fig. III) and crank with handle E", said shaft being journaled inbearings provided on the outside of f'rame F, (see Fig. Ill,) andcarrying` niiter-wheel E, imparting motion therewith to ruiter-wheel E3on shaft E", said shaft being journaled in bearings and brackets EB,(see Fig. IL) secured to frames F, and carrying miter-wheels E",imparting motion thereby to miter-wheels E, said wheels E being keyed toscrew-spindles El, said spindles being supported by brackets EB, andengaging with their threads to nuts E", said mits being bolted to eachof the two end brackets, S5, of the shuttlc-carriage. The turning ofcrank E2, therefore, will turn shaft E" and spindles El, and will windthe shuttle-carriage forward or backward.

The sh little-carriage is constructed, like the needle-carriage, with apipe, (see Fig. lI,) supporting a convenient number ofvertical brackets,S5, saidbrackets at their top and theirbottom, and carrying cast-ironstraight bars SoSo, one foreach row of needles, said bars serving assupport for the shuttles S and the shuttleslides S. (See Figs. 1V andV.) The straight bars SO S0,of which in this case there are two,are notdirectly bolted to the vertical brackets S5 S5, but there areintermediate angle-pieces, S2 S3, bolted between said angle-pieces S2and the further angle-pieces S3, which latterare bolted on S", formingthe two guideplates, between which the shuttle-slide S is guided justunderneath the straight bar S0. (See Fig. IV.) Through this bar S0,andcorresponding to each needle of the needle-carriage, vertical holes aredrilled, recessed at the top, and tted therein are small crank-shafts S,said shafts S6 provided at their bottoni end with a small crank, Sl, andat their top with a ring-shaped head-piece or collar, S8, at thehorizontal top face of which,and ontheperiphery thereof,are rigidlyfixed the piu SJ and the projection S10, almost diametrically oppositeeach other, said pin and projection having for their object to work theshuttles S whenever crank-shaft S6 with collars S8 are oscillated.

The shuttles are constructed as follows: A,

IOO

small dat bobbin,s, (see FigVL) is placed hori-` zontally in andencircled by an irregularlyshaped annular casing, s2, said annularcasing at its bottom opening supporting the bobbin by means of a narrowrim, 89, and being provided at its top rim with a suitable curved hingedspring, ss, which hinged spring can be swung up or down, being fulcrumedin hinges,

said hinges fast to the annular casing, said hinged spring s8,when it isswung down on the surface of the bobbin so, lying close over the upperopening of casing s2, thereby holding down bobbin so, and preventing itfrom jumping out; when it is raised, however, allowing said bobbin to betaken out and to be Y lled with new thread. The outer periphery of theshuttle or of the annular casing is of irregular shape, and, roughlyspoken, of halfcircular and halfrhomlo shape. The curved part ends onone side in a horn or hook, s, and on the other in the acute angle ofthe rhomb. rlihe straight sides of the shuttle-periphery are 1intendedto be acted upon by the pin S11 and thread against the face si, in orderto act as a brake on the thread; and in order to bringv said spring s1to bear upon the thread a ne saw cut or slot, 85, is made above saidspring into the upper rim of the shuttle-casing s", into which thethread is drawn from the bobbin so, and by means of aslot andloophole,s6, very much like through the arrangement in sewing-machine shuttles,the thread is brought under the springv s4, and by the pressure thereof,which may be regulated by the screw 311, a continuous and constant dragor tension is put on the thread, said thread passing from loop-hole sthrough a hole, 81?, drilled into spring lever SS. lThis hole beingcoincident with the center of oscillation of the shuttle, in order tohave the thread constantly and evenly stretched when the shuttlevibrates, acts as a guide for the thread, and the. whole arrangementprevents the lever ss from raising while the machine is at work.

In order to prevent any damage to the needles by striking theshuttle-casing, the needles having to approach the shuttles close enoughin order to cause the loop of thread to be engaged by horn s of theshuttles, a hole, 87, is drilled into the casing s2, near the horn orhook s, at the very place where the point of the needle enters, theshuttles being at rest in lthis moment. The needles then begin toretire, the loop forms on the thread, and the shuttle, beginning toswing around, engages said loop at once with its horn or hook, said hornor hook being slightly curved upward, and, like the whole shuttle,,nished crank-shafts S1 are tted, will rest with the middle portion oftheir bottom face, and simply by their own gravity, over the top ofcollars SS, which are fitted to the top ends of shafts S, and heldthereon. by means of setscrews. (See Figs. IV and V.) The recessed partsS11 have only the object to keep the shuttles always on the collars SS,and to prevent said shuttles from being thrown oi'i laterally,

or in horizontal direction. The plates S1"and S11, however, prevent anyvertical displacement of said shuttles. Projection S9 will come to bearagainst the straight face s3 on the periphery of the shuttle-pin S1",however,

into the cavity s', formed by the other straight face of the peripheryof the shuttle, and by hook or horn s. Shuttles S,therefore,are forcedto follow any oscillating motion imparted to shafts S6 and to thecollars S8. wherein the shuttles are resting a vertical strip ofsheet-iron,S14,is screwed up against cast-iron bar S0, facing thefabric-carrying frame, the shuttle-carriage being so close up againstthe Close to -holes fabric-frame that the plane of the fabric nearlytouches sheet-iron S11. In this sheet, called the needle-sheet,77 andopposite each needle of the needle-carriage, holes are provided,(seeFig.lV,) into which holes the needles,together with the thread drawnthrough their eyepoints,will enter while piercing the fabric, and willadvance until about half thelength of the needle N has entered saidholes in sheet S14, and until the eXtreme point of the needle hasentered the hole s1, provided in the shuttle-casing. The relative heightof the needles N and of the point of the hook s of the shuttle is nowthus devised that-said point of hooks strikes close underneath needle Nat a point very close to sheet S14. The shuttles before beginning theiroscillatory movement are in such a position relatively to theneedle-thread that their hooks are close to the loops which are formedby the same underneath the needles,owing to the friction of the threadin the comparatively narrow holes of sheet S1*,while the needle-carriageis retreating from the fabric. The shuttles, therefore,when oscillatingfor about two hundred and twenty degrees, will engage said loops atonce, and, having engaged the same, will slip through, which' process isgreatly facilitated .by the rounded shape and smoothness of the'polishedshuttles; but by slipping through said loops the shuttles will also drawthe thread Wound on the IIO bottin 80 0f the Shuttle and passed through'I hole S1o of lever sB through the loop formed by 'by the needle islocked up.

the needle-thread. Thereby the stitchl made It is important that theprojection S9 and the pins S10 on the upper faces of the collars or headpieces Ss for each shuttle be rounded off at their tops and polished up,first, in order to permit the thread of the needle to slip betweenshuttle and the parts whereon said shuttle rests, and, second, in orderto secure the slipping back of the shuttles into their regular andoriginal position whenever they might have been displaced by thefriction and pull exerted by the contracting loop of the needlethread.It has been found as most convenient to swing or oscillate the shuttlesfor each lockstitch at an angle of about two hundred and twenty degrees,which will be sufficient to engage the loop and to slip the shuttlethrough said loop and tighten up the shuttle-thread. The shuttles, afterhaving slipped through said loops by their oscillation of two hundredand twenty degrees, swing back again for the same two hundred and twentydegrees, and are ready for a new stitch. The relative movement of needleand shuttle is thus ar- 'ranged that a continuous pull on theshuttlethread is produced,whieh otherwise is necessary to give even andclean work. This oscillation of two hundred and twenty degrees of theshuttles is produced by the crank-shafts S, said crank-shafts carryingat their bottom end cranks, Swhich are connected by means ofconnecting-links S15 to pins S16, which are rigidly fixed in theshuttle-slide S. This slide S, of which there is one for each row orseries of shuttles, has a rocking and at the same time acircularswinging motion,moving, however, always parallel to itself, whichparallel motion is accomplished by the parallel linkmotion. Two pins, S,are fast, one near to each end of the stationary bar S0, and said pinsS17 are linked each by a link, S18, to apin, S19, secured to each end ofthe slide S. In order to secure now a parallel and circular swingingmotion of the slide-bar S, the distance at which the pins S19 are setfrom each other is made equal to the distance between pins S", and bothlinks Sx8 are made of equal length. The links S1B will therefore bealways parallel to each other. In Fig. IX only one of the links S18 isshown-the one at the right end of the slide S. The rocking motion isderived for each slide-bar S by means of an adjustable rod or link S2",which is linked to the right hand end of slide S. As there are two rowsor series of needles and shuttles,there are also two bars, S", and twoslide-bars, S. At each right-hand end of the latter such an adjustablerod or link,S2,is provided, and said links Si are easily disconnectedfrom slides S', by taking out pins S21. This disconnecting becomesnecessary when the shuttle-earriage has to be slid backward off from itsn ormal-that is, its working-position, either for hole-punching, or whena new cloth has to be stretched on the fabric-carrying frame. Links S29are linked to the two levers D8, said levers keyed one to the top andthe other to the bottom end of the vertical shaft D6. Said shaft D6 isprovided on the right-hand frame F, and is mounted in bearings D9 D,said bearings being secured to said frame F, and shaft D6 is crookedtwice between said bearings, so as to form a double crank, D7. A slottedcross-head, D5, engaging said crank D7, is also connected by link D* toa slotted cranklever, D3, said crank Di1 being fulcrumed on pin D2, pinD2 being screwed rigidly fast on a bracket which is fast to themachine-frame F. This shaftDG is occurring only once in the machinetowit, on the right-hand side frame of the same, as illustrated in Figs.VII, VIII, and IX. The slotted crank-lever D3 is swung to and fro by pinD10, moving in the slot of crank D3, said pin D10 being arrangedeccentrically to the driving-shaft D on the eccentric-disk D12, which isconnected with the right-handside connectingrod. Said connecting rod,therefore, as well as link Dt, will have an oscillating rocking motion,the rst rocking, by means of cross-head N2, the needle-carriage, and thesecond rocking, by means of cross-head D5, the crank D7 of shaft D6. Inorder to guide the cross-head D5 properly, the guide-head Du is providedon cross-head N2 of the needlecarriage, the guide rod D13 sliding insaid sleeve D11 and being secured to cross-head D5. It must be statedhere that, as has been shown, the mechanism for rocking theshuttle-slides occurs only on the right-hand side ofthe machine.

It remains now to fully explain that the combination of the rockingmotion ofthe shuttlc-slide bar S with the circular swinging motion ofthe same produces the desired oscillation of the shuttles for about twohundred and twenty degrees. As will be understood from Figs. IV and V,and from the matter described in the above, the shuttles rest freely bytheir own gravity on top of the collars S8 and crankshafts S, and areforced to take part in any horizontal oscillating movement which may beimparted to said shafts, because the pins or projections S10 and S9prevent any displacement or rotary movement of the shuttlesindependently from the collars SB and crank-shafts S6. In Fig. V the twoeXtreme positionsof the crank-shafts S with shuttles are given in onerepresentation. The position of said parts is shown after the shuttlehas slipped through the loop of the needle-thread, and in the otherrepresentation the same parts are shown ready to begin the oscillationof two hundred and twenty degrees. In Figs. IV and V part of theshuttle-slide bar S is shown connected to the cranks S7 of crank-shaftsSG, and said slide S is also in its extreme position. The slide willexecute a circular swinging movement to the left, describing nearly halfa circle, said halfeircle having a radius equal to the lengths of thelinks S, one of which is shown in Fig. IX. At the beginning of thismovement in a halfcircle the slide S will be moving at first almostrectangularly off from the bar S0, and owing ICO IIO

to this fact, and by means of the links S15, will turn the cranks F7 ofthe crank-shafts in the same direction as thehand of a watch. Ow-

ing, however, to the fact that cranks S7 and V. Slide-bar S reversingnow its circular oscili latory movement, will oscillate the crank-sh aftS6 back again, together with. the shuttles, and will bring the sameagain into the position shown sub b, Fig. V. Thus it will be seen thatthe revolutions of shaft D will rock the needle-carriage, as well asproduce the desired movement of the shuttle, and besides that it will,by moving the needle-carriage, operate also the take-up andcloth-pressers.

On the left-hand side of the machine, where the attendant is sitting,andwhere the handle I)0 (see Fig. I) of the pantograph P is located, thedriving-pulley D0 is keyed to the shaft D of the machine. An ordinaryfriction-clutch, K, is combined with said pulley D0, said clutch beingconnected with levers and rods to the foot-rests of the machine,so thatby the operating of said foot-rests the attendant is free to stop orstart the machine. This stopping or starting arrangement by means offoot-rests and friction-clutch is not new in embroideringmachines, andit will not be necessary to describe it any further; but the brake ofthe pantograph connected therewitli,for1ning part of my invention,isnew, and I give herewith a detailed description. First, it may beobserved that an additional frame, F0, has been set up on the left-handside of the machine, supporting the friction-clutch K as well as theshaft It, whereon the levers of the foot-rests are keyed, and carryingalso a bearing, D', for the end of shaft D. The brake of thepantographhas for its object to secure the respective position of handle-rod l??while the machine is stopped, thus facilitating greatly the work of theattendant and preventing any in jury done to the pattern drawing by thepointer or pencil secured onl the handle-rod ofthe pantograph. Saidbrake has to operate simultaneously with the downward movement of one ofthe foot-rests, and will clamp handlerod P0 of the pantograph betweentwo horizontal rods whenever this operation is performed. Foot-rests Band It2 are provided at the ends of two levers, the other ends of saidlevers fulcrunied on a shaft, B, said shaft supported between frames Fand Foi The vertical rods B and B2 (see Figs.I and III) are linked thelevers of the foot-rests at points between the .fulcrums and thetreadles of the footrests, said rods being linkedto two ends of aT-shaped lever, B3, said lever fulcrumed in pin B0 and operating withits third and vertical end the friction-clutch K. Pin B1 is y. rigidlyfast to a frame vconnecting the frames therefore, is the startingfoot-rest. R,

is linked on said lever B3, rod B7 being linked y. with its upper end toa horizontal lever, Bf,

said lever keyed to a horizontal shaft, B9. This shaft B9, running alongthe pattern-board Z, carriesat each end a vertical lever, the ends B7and Bs of said levers being linked by rods B5 B5 to two slides, B10 B71,sliding in a horizontal slot provided within brackets B12, said bracketssecured rigidly one to the frameF of the machine andthe other to anauxiliary column or rod, V. The slides are thus eonnect- Y ed that bythe oscillating of shaft B9 the slides B10 B11 will either approach eachother or slide apart, and the slides on both sides of the drawing-boardsZ are connected by two parallel rods, so as to bring said rods togetheror apart, corresponding to the movement of the slides. The handle-rodP0, hanging down in front of the pattern-board, is arranged between theparallel slide clamp rods B10 B10 and Bu B, so as to be clamped by saidrods whenever they approach each other sufficiently, and to be ieleasedagain when said rods part from each other. Pressing down now thefoot-rests R,(see Fig. IIL) rod B4 will pull lever B6 down, and by meansof shaft B9 and levers B7 B8 and the connecting-links will TOO cause theslides and rods B10 Bu to approach each other and to clamp rod P of thepantograph between them. It will therefore be observed that thehandle-rod P0 is clamped when the machine is stopped and let free whenthe machine is Started.

The hole-punching apparatus (see Figs. II

and X) is of similar construction in almost all embroidering-machinesproducing open embroidering-patterns. In my machine, however, it islocated on the shuttle-bar S0. It consists in a number of smallbrackets, O O', secured tothe top ofthe cast-iron bar S0 of theshuttle-carriage, and carrying in hinges'a rail y of angle-iron, O, saidrail being provided with as many awls Oz as there are needles in theneedle-carriage. Said rail 0 is located so that when it is swung down,ready for the hole-l punching, the awls will correspond to holes O3,provided for this very purpose in the rail.

H7 of the cloth-presser, the rail H0 serving here as support to thefabricfor the punching process. Vhen said bar Oo is swung back,

however, it will not obstruct in any way the workin g of the shuttles ofthe shuttle-carriage,

and will be held in each position-to wit,when being swung back or down,simplyby its own gravity.

Whenever holes have to bepunched into the fabric, the machine has to bestopped and the shuttle-carriage to be disconnected from links S2 bytaking out pins S22. This will allow to slide the shuttle-carriage backby crank E2, whereupon rail 0 will be swung down and theshuttle-carriage slid forward again against the fabric by crank E2. Theholes being punched, the shuttle-carriage is slid back and the rail O0swung up and the shuttle-carriage slid forward again, in order to bringit in its original position, and to connect it again with links S20 byputting in pins S21, whereupon the embroidering may go on.

In order to make fully clear the manner of connection and transmissionof motion between driving-shaft and needleearriage, cloth-presser, andtake-up, I shall describe said parts with reference to drawings XI, XII,and XIII. It must be stated, however, that for convenience sake, and inorder to makethe drawings as clear as possible, several parts have beenomitted and shown in more simplified shape, as will be particularlystated in its proper place.

In Fig. XI theleft-hand end of the machine is shown, frame F0 beingomitted, and also all parts constituting the takenp, the cloth-presser,the shuttlecarriage, the pantograph, and the fabric-carryingframe. Insaid Fig. XI the doubled crooked part D2`L of the driving-shaft D isshown, said shaft being journaled within eyes cast to each of the framesF, only one being shown. The crank D2* islinked by means of theconnecting-rod N and the cross-head N2 to the slide-block N3 at the leftend of the pipe N4 of the needle-carriage. In a similar Way theeccentric-disk D22, as has been explained already in the above, isconnected to the block N2 at the right end of pipe N*, as is shown inFigs. VII and IX. The blocks N3 are made to slide on the guide-bars F2,which are secured one to the inside of each frame F. Brackets N5,secured to pipe N4, are supporting the needle-bars N0, unto which theclamps N6, holding the needles N, (see Fig. V,) are secured rigidlyfast. lVhen shaft D revolves, the needle-carriage, together with theneedles, will receive a to and-fro movement.

In Fig. XII the same side ofthe machine is shown as in Fig. XI, Frepresenting the side frame of a machine partly broken off, N3representing the slide-block of the needle-carriage, unto which theconnecting-rod N is sleeved by means of head N2. Said connecting-rod isshown engaging the crank D14 of driving-shaft D and bearing unto the endH7 of arm H6, which arm is secured rigidly fast at the end of the smallshaft or pin H8. This shaft H2, with accessory parts, occurs on eachside of the machine.

As shown in Figs. VII and IX, it will be preferable to provide the endof lever H6 with a journaled friction-roller, H7, which, however, isomitted in Fig. XII, in order to make the drawings as plain as possible.The pin or shaft HS is journaled within an eye cast onto the frame F,and carries at its other end, secured rigidly fast, another short arm,H2, the end of which engages, by means of a forked or slotted part, apin secured within the vertical rod H5. In Figs. VII and IX, however,the slotted part is provided on the rods H2, and the end of arm H9 isprovided with a pin engaging said slotted part. As a matter of course,the construction shown in Figs. VII and IX and the one shown in Fig. XIIare equivalent, and may be substituted for each other. The rod H5,which, as indicated in the matter above, is duplicatedto wit, one rodfor each side of the machine-connects the arms H2 H2 of the angularlevers H II2 H H2, which are supporting the rails H0 H0 of thecloth-presser by means of their arms H H. The angular levers H H2 H H2are provided with pins se cured rigidly fast into the angle portion ofthe same, and arejournaled by means of the same pin into brackets H3 H2,which are bolted unto frame F of the machine. It will now be understood,when rod H5 is rocked downward and upward, that the rail Ho of theclothpresser will oscillate horizontally off from and toward thefabric-carrying frame, which may be seen in Fig. II, and which issuspended facing the horizontal rails H0 of the clothpresser. The rodsH5 are connected to the ends of arms H2, as indicated, and said arms H9are keyed fast to small shafts H2, which are journaled in the frames F,as shown also in Figs. VII and IX, and therefore when the arms I whichare also fast to the small shafts H2, are oscillated by contact with theoscillating connecting-rods N the rods H5 and the rails H0 will also beoscillated. The arms H6 are made to bear constantly against theconnecting-rods N by the gravity of the rails H0. This gravity would besufficient in itself to secure the continuous contact between arms H,asshown in Fig. XII, or the journaled friction-rollers H1 at the endsthereof, as shown in Figs. VII and IX, and between the conneeting-rodsN. However, it has been thought advisable to secure this contact stillbetter by providing helical contracting-springs H22, attached to theframes F and to the ends I-IT of arms H,with a view also to increase thepressvure of the rails H0 on the cloth when the connecting-rods N N arein their most elevated position.

In Fig. XII, the left-hand side of the machine,with the parts of thecloth-presser just described, is shown, and it must be stated here thatthe right-hand side of the machine is similarly arranged. Vhen theneedle-carriage is moved off from the fabric, and when theconnecting-rods N are assu ming their high est position, or, in otherwords, when the needles withdraw for tightening the stitches," the railsHo will swing against the fabric and keep the same back from following,and thus will prevent any distortion of or injury to the IOO B2, rod B2,lever B5, shaft B", levers B2 B5, conmeeting-rods B5 B5, brake-slidesB20 B22, bracket B22, frame F and F2, stand V, shaft D, pulley D, andthe pantograph-handle P22.
